Langjökull

Dropped by the Icelandic Met Office site and noted the illustrated strong Earthquake swarm about thirty kilometres northeast of the Langjökull glacier. As usual, without other data there are no conclusions as to what, if anything, this portends. Still, four tremors of 3.0 and above plus supporting cast in a very small geographic area indicate either there's something bubbling under, or there's a small highly localised war going on.

Update: A level 4 shock has occurred in the past twelve hours within the critical 10km depth range. Something's having an active Halloween. Maintaining a watching brief.

Update: While the Eyjafjallajokull volcanic eruption in Iceland is declared over, news is breaking of a suspected sub glacial eruption at the Grímsvötn volcano. The much vaunted Katla remains quiescent.
